Setup IP address

R1:

enable
configure terminal
  interface ethernet1/1
    ip address 10.0.1.1 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 10.1.1.1 255.255.255.252
    no shutdown
    exit
 end

R2:

enable
configure terminal
  interface ethernet1/1
    ip address 10.0.1.2 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 10.1.2.1 255.255.255.252
    no shutdown
    exit
  !
  ! NAT GNS3 gw 192.168.122.1
  interface ethernet1/3
    ip address 192.168.122.100 255.255.255.0
    ip address 192.168.122.101 255.255.255.0 secondary
    ip address 192.168.122.102 255.255.255.0 secondary
    no shutdown
    ip route 0.0.0.0 0.0.0.0 192.168.122.1
  end

R3:

enable
configure terminal
  interface ethernet1/1
    ip address 10.1.1.2 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 192.168.1.1 255.255.255.0
    no shutdown
    exit
  end

R4:

enable
configure terminal
  interface ethernet1/1
    ip address 10.1.2.2 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 192.168.2.1 255.255.255.0
    no shutdown
    exit
  end

Setup OSPF

R1:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf 1
  network 10.0.1.0 0.0.0.24 area 0.0.0.0
  network 10.1.1.0 0.0.0.3 area 0.0.0.1
  end

R2:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf 2
  network 10.0.1.0 0.0.0.24 area 0.0.0.0
  network 10.1.2.0 0.0.0.3 area 0.0.0.2
  end

R3 configuration:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf 3
  network 10.1.1.0 0.0.0.3 area 0.0.0.1
  network 192.168.1.0 0.0.0.255 area 0.0.0.1
  end

R4 configuration:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf 4
  network 10.1.2.0 0.0.0.3 area 0.0.0.2
  network 192.168.2.0 0.0.0.255 area 0.0.0.2
  end

Cek route
